cpp2c

Hand-written translation of C++ object-model features into C.

Based on a PublicTransport class hierarchy: constructors / destructors, copy/assignment, inheritance-by-embedding, vtables, virtual dispatch, polymorphic containers, and template-as-macro (MAX_FUNC).

C++ → C mapping (highlights)

C++	C in this demo
class / private data	struct + nested private struct
constructor / destructor	XxxCtor / XxxDtor
virtual function	function pointer in vtable
inheritance	embedded base struct
new / delete	malloc + ctor / dtor + free
template	preprocessor macro (MAX_FUNC)
